Hey there, Swagrid.
As far as I know that model has an SD card reader and you should be able to use a memory card for some extra storage space. On the other hand, I've read some threads in the past about people trying to upgrade the computer with an extra SSD/HDD as it seems like the netbook has an extra proprietary connector of some sort and a drive bay, but you should check the netbook manufacturer's community for more info on that.
Basically you should be able to find info in the computer's "User's Manual" on what can be upgraded in terms of hardware and what can't. My suggestion is to contact the netbook manufacturer's customer support if you have any doubts whatsoever and ask for assistance, just to be on the safe side.
Hope that...
